Webtechniques were used to observe mitosis in the tip of onion root cells during actively mitotic division cells time. MATERIAL AND METHODS Actively dividing cells from an onion root are removed and treated with hydrochloric acid to fix the cells or to stop them from dividing. The cells are then stained, made into a wet mount, and squashed.
WebMitosis – actual division of DNA and organelles; cell membrane pinches in Cytokinesis – division of the cytoplasm; two daughter-cells formed What would happen if our cells didn’t go through interphase correctly? DNA replication happens in interphase, so a problem is most likely to happen then. WebMitosis is the process of cell division that Walther Flemming named after himself. The root tips of sprouting seeds and bulbs undergo rapid cell division. When studying mitosis in labs, the root tips of onion, wheat, lentil, barley, and alfalfa are most commonly used for …
